[Cialug] Ubuntu 12,04 LTS

Tue Nov 19 00:04:42 CST 2013

You are correct.  Canonical seems more concerned about delivering a "pretty" system that works at a respectable level of performance than they are about covering the widest user base.

I wasn't paying a huge amount of attention to when the liveCD (liveUSB) install option was reported to have been attempted, so I may have made the wrong guess about the issue (though I do stand behind the fact that this is an extremely common cause of the problem of having a broken system after upgrading from pre-12.04 to 12.04 and later).  If you were able to boot into Unity on the liveCD/USB media, then I can only assume that you have hardware 3D acceleration support.  I haven't paid enough attention as to whether the live install media has the same 3D hardware requirements that the final install of Ubuntu does, but I can only imagine that it does.  If the live media boots and gives you a running Unity GUI, then I would be willing to assume that the system should run equally well after a successful installation.

My first troubleshooting step would be to make sure that the md5sum of the ISO download matches.  You might also want to run a check against the USB drive you are trying to install from (if you haven't already).

I assume that this is true in any versions greater than 12.04 as well then.  Is that correct?

The biggest -- or maybe "most common" -- issue that people upgrading to Ubuntu 12.04 are facing is that Ubuntu has completely dropped support for software 3D rendering in Unity, which means that any system without a supported 3D graphics card can not run Ubuntu 12.04 in graphical mode.  You can get a cheap, ancient graphics card that is supported, or you can choose a different GUI.  I've been using Xubuntu (XFCE) on my little ARM dev boards when I need to use an Ubuntu install since Unity doesn't properly support OpenGL ES2 as implemented on the dev boards I use.  You can also use Lubuntu (LXDE), and I'm pretty sure that KDE can still run using software rendering in Kubuntu.

It could always be a completely different issue, but that is the most-complained-about problem with 12.04.
